I am using basic authentic for http connection in app. App is working finr correctly on devices with higher versions. I have also searched for solution and It did not worked for me. Here is my code for connection
public static String executeHttpPost(Activity activity, String url,
                                     ArrayList<NameValuePair> postParameters) {
    String value = "{\"status\":false,\"message\":\"Server Timeout, connection problem, Please try later\"}";
    try {
        final String basicAuth = "Basic " + Base64.encodeToString(
                ("abc" + ":" + "abcd").getBytes(), Base64.NO_WRAP);
        networkConnection = new NetworkConnection();
        if (networkConnection.isOnline(activity)) {
            postParameters.add(new BasicNameValuePair("device_type","android"));
            HttpClient client = getNewHttpClient();
            HttpPost post = new HttpPost(url);
            try {
                UrlEncodedFormEntity entity = new UrlEncodedFormEntity(postParameters, "UTF-8");
                post.setEntity(entity);
                post.setHeader("Authorization",basicAuth);
                post.setHeader("some-parameter","abc");
                org.apache.http.HttpResponse result = client.execute(post);
                value = EntityUtils.toString(result.getEntity());
            }catch (Exception e){}
            String s = "";
            for (NameValuePair param : postParameters) {
                s = s + param.getName() + " = " + param.getValue() + " ";
            }
            if (value != null) {
                WebUrl.ShowLog("From " + url +" parameters "+s
                        + " Response : " + value.trim());
                return value.trim();
            } else {
                return value;
            }
        } else {
            activity.startActivity(new Intent(activity, NoInternet.class));
            activity.finish();
            return "{\"status\":false,\"message\":\"\"}";
        }
    } catch (Exception e) {
        e.printStackTrace();
        return value;
    }
}
